A powerful cold front will arrive late Friday into Saturday, bringing the coldest temperatures of the season. The cold air will overlap with some lingering moisture behind the cold front, leading to the potential for freezing rain or sleet Saturday into Sunday. This is still several days away, so please monitor the forecast for any changes. Stay weather-aware, prepare now, and consider adjusting your travel plans for the weekend.
Confidence is increasing in very cold air this weekend. Confidence is moderate to high that temperatures will fall well below normal after Friday and will persist through at least early Tuesday. Confidence is low on how cold will Southeast TX be.
The coldest conditions are expected late Sunday night into early Monday morning. Temperatures will likely plummet into the upper teens for inland areas and the upper 30s along the coast. A hard freeze is increasingly likely Sunday night, with wind chills potentially dropping into the single digits across parts of Southeast Texas. This graphic shows the probabilities for temperatures reaching critical thresholds of 32°F, 24°F, and 15°F.
A weak coastal low will bring scattered showers and isolated thunderstorms to the area Wednesday. Coverage will be greatest in the afternoon and along the coast. Generally looking at rainfall totals of up to 0.25-0.5", but locally higher amounts possible along the coast.
A Low Water Advisory remains in effect for Matagorda Bay through 6 PM this evening and Galveston Bay through 10 PM Tuesday. Negative tide levels expected with the lowest water levels around low tide cycles, and especially in the northern and central bay areas. There is an increased chance of vessel grounding.
